• Short pitch cables for special application
• High performance optical network operating in O-E-S-C-L band
• High speed optical routes in buildings (FTTx)
• Cables with low bending requirements
YOFC EasyBand® bending insensitive single mode fibre meets or exceeds the ITU-T Recommendation G.652.D/G.657.A1 including the IEC 60793-2-50 type B1.3/B6.a1 Optical Fibre Specification.
• Low attenuation satisfying the operation demand in O-E-S-C-L band
• Good bending loss resistance at short radius bends
• Low bending loss for highly demanding cable designs including ribbons
• Low PMD satisfying high bit-rate and long distance transmission requirements
• Accurate geometrical parameters that insure low splicing loss and high splicing efficiency
